" and VWiLLARD C, SMITH, .citizens 'oftlie `United States, `and residents of 'fSiouXfCity. in the county .of Woodbury and "Statel of Iowa, have invented -certain 'new 'and useful improvements iin 'Oil-Vapor Burners, of. which the following isa spelcilic'ation.

the .productionof an improved "gas burner.

While We have :illustrated butone form of the invention, We would not be understood as'being limited to sueh rspecific construction Vfor various alterations and 'modifications may be made 'in thedetalls of con-struction and arrangements of parts herelndlsclosed without departing from 'the spirit and scope of the invention asv defined in theappended claim.

clear.

The nozzle is bottom of the pan and around an opening, v

22,.- in [the bottom thereof. through saidopening, 22,A is a short tube, 23,

havingits upper endthreadedinto the`noz 95 l j .zlefbodyl head, 9. Into the .lower end of they tube, 23,"exten'ds one end of asmall tube, 24, 'preferably'of semiflexible material, as` copperftubing, `the -lfp'weiendp` portion of saidv tube, 23, being provided With 'a counterbore, 25,1150 Vreceive al glandnut, 26,to kform Va Ygas-j d' tight"connectionbetween the tubes, 23 and v24; The'tube, 241is' bent laterally and has Y its otherend inserted'fin a tube, 27, and lirmlyk securedf therein* by a glandg'nuu v28,

screwedlonto the tube, 27, and firm en-` no gageinent with the plate, 31, the latter being secured to the part', 1,:by a bolt, 34', or otherwise.

The outer endportion of the tube, 27, is provided with a counter bore, 35, in which freely reciprocates a plunger, 36, encompassed by a gland nut, 37, screwed onto the tube, 27. To one end of the plunger, Y3.6,'is

ysecured aiwire, 38, which passes through the guide tube, Y Q11, and upwardly through kthe tube, 23, the nozzlebody, 8, and into the noz-r Zle jet, 15, the wire being ofsuflicient length that when the plunger is forced inwardly 'the wire will project through the jet opening, 18,

and movement ofthe plunger in the'opposite direction withdraws the wire from thejet opening-18, Vsufficiently to place lthe end of the wire within the counter bore, 19. The

tapered end, 20, ofthe counterv bore, 19a ,20

serves to ing, 18. v e

Now, it will be vclear that liqr'nd fuel en- Vguide the wire into the jetopen ,tering the retort receptacle, 5, from the passages, 6 and vwill be convcrted'into gas by the heat fronrthe jettherebelow, and the gas is conveyed to the jet through the' passage, L1, and nozzle body, 8," ln thisKt-ype of burner'we do'not' burnthe liquid fuel as is usualin liquidfuel burners, but 'rather the oilis converted into. va vor'be'fore beine" introduced into the nozzleand,` furtherf niore,`wefd o not control the liquid fuel supply as is `usual in` liquid fuel burners to regulate the heat,eb`ut 'rather we control the gas at the jet by extending` and retracting' V the throttle-wire, V38, into and Yfrom the 'jet opening, 18, toV accordinglydecrease or inl creasethe flow of gas from the iet.'

The plunger, 36,'is preferably controlled 'j by a lever, 39, ful'cruniedV at its center, as at l1:0, to a suitable f bracket-arm, 41, on the plate, 31; and having a central depending arm, 4:2, connected by a toggledink, 43, with the plunger36, whereby oscillation of the said lever, 39, willl extend andv retract the throttle-wire. The opposite ends 0f the lever, v

39,1nay be connected to the usual furnace draft controlling chains, 44, and if desiredy these may be automatically controlled by a therinostat.` f i Having thus described our invention, what we claim as new and desire to secure by Letters Patent ofthe United States, is:

4 An oil-vapor burnerfor a heater having lan enclosingr wall-part, `embodying a retort i receptacle adapted to `be positioned within ftheL heater` and receive yoil from a ,source 0f sired position, including ya bracket arin vadapted to` be niounted on said wall part, a vlever fulcruined on ther arm, and an opern ative connection between the lever and wire. ln testimony whereof, we have lhereunto yset our hands this 19th dayof October, 1921. f NELSON WARREN.
